<h4><a name = "tag_000_007_1126">&nbsp;</a>NAME</h4><blockquote>
pthread_attr_setdetachstate, pthread_attr_getdetachstate
- set and get detachstate attribute
</blockquote><h4><a name = "tag_000_007_1127">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;<a href="pthread.h.html">pthread.h</a>&gt;

int pthread_attr_setdetachstate(pthread_attr_t *<i>attr</i>, int <i>detachstate</i>);
int pthread_attr_getdetachstate(const pthread_attr_t *<i>attr</i>, 
    int *<i>detachstate</i>);
</code>
</pre>
</blockquote><h4><a name = "tag_000_007_1128">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>detachstate</i>
attribute controls whether the thread is created in a detached state.
If the thread is created detached,
then use of the ID of the newly created thread by the
<i><a href="pthread_detach.html">pthread_detach()</a></i>
or
<i><a href="pthread_join.html">pthread_join()</a></i>
function is an error.
<p>
The
<i>pthread_attr_setdetachstate()</i>
and
<i>pthread_attr_getdetachstate()</i>,
respectively, set and get the
<i>detachstate</i>
attribute in the
<i>attr</i>
object.
<p>
The
<i>detachstate</i>
can be set to either PTHREAD_CREATE_DETACHED or PTHREAD_CREATE_JOINABLE.
A value of PTHREAD_CREATE_DETACHED causes all threads created with
<i>attr</i>
to be in the detached state, whereas using a value of
PTHREAD_CREATE_JOINABLE
causes all threads created with
<i>attr</i>
to be in the joinable state.
The default value of the
<i>detachstate</i>
attribute is
PTHREAD_CREATE_JOINABLE .
</blockquote><h4><a name = "tag_000_007_1129">&nbsp;</a>RETURN VALUE</h4><blockquote>
Upon successful completion,
<i>pthread_attr_setdetachstate()</i>
and
<i>pthread_attr_getdetachstate()</i>
return a value of 0.
Otherwise, an error number is returned to indicate the error.
<p>
The
<i>pthread_attr_getdetachstate()</i>
function stores the value of the
<i>detachstate</i>
attribute in
<i>detachstate</i>
if successful.
</blockquote><h4><a name = "tag_000_007_1130">&nbsp;</a>ERRORS</h4><blockquote>
The
<i>pthread_attr_setdetachstate()</i>
function will fail if:
<dl compact>

<dt>[EINVAL]<dd>
The value of
<i>detachstate</i>
was not valid

</dl>
<p>
These functions will not return an error code of [EINTR].
